Carbon Dioxide: A Natural Alternative | Cooling India Monthly …

15/11/2018· Carbon dioxide was first solidified in 1835 by a French physicist, Thilorier and from then it is being used as a cooling agent, popularly known as dry ice to solidify mercury. Lowe was first to suggest that carbon dioxide could be used as a refrigerant in 1867. In 1884, Raydt built a R744 (CO2) refrigeration system for making ice using a vapour compression mechanism while, at the same time, J …
